lBe it known that i, lil/'rement Semeuse a citizen oi' the llnitedStates7 and a resi-- dent olf Toledo, in the county or" Lucas and Stateof Uhio, have nade an invention Appertaining to lolleulgearings; and lvdo hereby declare the following to be a full,j clear',a.nd exactdescription of the inventiom lsuch as will enable others skilled in theto Which it appertail'is to make and use the saine,i reference beinglhad to the e-ccoinpanyH ing drawings9 and. the characters of rei Ierencernariied thereoin which torni a jpart ci' this specification ll/lyinvention has :tor its object to reduce the Wear in roller bearings. ltalso has for its object to provide in roller bearings ineens whereby therollers and the cup may be assembled used as a unitary structure, thatis, it has igor its object to provide a rneansv whereby the rollers aresecured. Within. the cup and vvill be maintained in the cup even thoiughthe cone be removed iroin the rollers. object other advantagesWhich'vvill appear i-rorn the' following description and uponexamination of the drawings.

The invention may be contained in structures of different-torens. Toillustrate the practical application ci my invention l have selected aroller bearing containing the invention and shall describe ithereinafter. rlhe roller bearing selected is illustrated in theaccompanying drawings. Y

.Figure 1l ci Vthe drawings illustrates an lfoiuter end view of thehearing. y l1" ig. 2 illustrates "afsectional and a broken 'view ot .the

The-larger diameters of the tapered rolt ylhe invention has for;

o; The cup' ilis provided with the usual Letters ers are at their innerends the distance between the conical surface of the cone and theconical surface ci:l the cup is consequently greater at their inner endsthan at their outer ends, IThe result is that When the cone or the cupis traveling' or moving relative to the other and particularly when theyare carrying a load the rollers tend' to Work.

inwardly, that is, out from between the inner ends or edges ci the @oneand cup. The rollers are usually confined and this inward relativemovement ot the rollers prevented by ineens oi a which is located on theinner end oi the cone. lf then there is any lateral thrust, particularlyas that produced in an autoinobife Wheel hub9 the ci the cone forces.nst the ends oi the rollers and causes increased pressure and a-Wear oncorners oil the rollers instead of causing the thrus 'o be sustained bythe much larger contact su laces, namely, the conical surface of thecone and cup and the tapered-surfaces of the rollers. ln the bearingscontaining niy invention ll have provided a cone or inale inernber Whoseentire contacting surface is an uninterrupted cone which permits theready separation of the cone or male member from the"'rollers and thecup and presents only a single cone bearing surface to the rollers. Therollers, however, are retained in position Within the cup by thecoaction ci theridge 4 which is located on thev inner end of the cup lathat is,' on the end having the larger inner diameten The ridge extendstoward the axis at the inner edge ofthe cone surface of the cup toengage the inner ends of the rollers. The ridge Il, being located on theedge of the cup having the larger diameter,7 is thus so located that noenvdvvise thrust produced by the lateral pressure or movel nient oi'sthe load is forced upon the ends of the rollers but theendwise 'thrustis sustained by the conical surfaces ci the cone and cup and rollers.V'llhe ridgeyliowever, operates to retain the rollers and cage in theirpositions with the cup when cone is Withdrawn.

The rollers arealso maintained inadelinite relation to each other bymeans of a suitable cage d. By :my invention is' pros vided ameansfvvhereby the cup l, the rollers and the cage may be assembled as asingle unitary structure,

'lfne cage d is provided with ribs that are lll@ i connected tothecircular ridge 8 and to the sinuous ridge 9, the ridge 9 being formed ofelastic metal continuous throughout, that is. formed of entire metal, isexpansible or contractible. The ribs have portions that are locatedwithin the imaginary cone surface that passes through the axes of therollers, and which are located in close proximity to the rollers whichoperate to hold the rollers against the inner surface of the cup. Theribs 7 may be provided with curved flanges l0 that conform substantiallyto the surfaces of the rollers 3. The rollers 3 may be placed inposition between the flanges 10 and then thel cup 1 may beplaeed overthe rollers and the cage and forced down upon the rollers, the

- ridge 4 will press against ,the lowe'r portions of the taperedsurfaces of the rollers and thus compress the contractible ridge 9 un#til the ridge 4 `is lforced over the lower ends ofthe rollers 3',whereupon theridge 9 will cause the end ofthe'cage to expand and thushold the rollers within the cup. Theentire bearing surface of the cup is'a conical surface, t and the cagevin position-when' the cone isWithdrawn, and for locating the rollers While fio the partsarefbeingadjusted.' AThe cone 2 may thusbe readil inserted orwithdrawnoperates also to greatly strengthen 'the c up portion ofthebearing. -In earings well e ridge operating to hold therollers known inthe art, the cups spread at the inner end that is, enlarge, due to thewed ing action of the vthrust ofthe cones. n such 'bearings the cups arestrengthened by adding metal to the outside of the cup.v #The ridge 4does away with this metal so that the cup can be made so as to have arelatively thin wall.`

I claim Y. l l; In a roller. bearing, a plurality of rollers havingtapered surfaces, a cup member having a conical bearing surface, a malebearing member located within the rollers,

:the entire contacting surface of the male bearing member being in theform of an uninterrupted cone surface, an inwardly extending ridgelocated at the edge of the conical surface `of, the 'cup' having thelarger diameter, the entire contacting surface of the cup, except forthe ridge, being the conical surface.

2. In a roller bearing, a plurality of l rollers having taperedsurfaces, a cup mem-` ber having a conical surface and an inwardlyextending ridge located at the. edge of the conical surface having thelarger diameter and anfelastic' contractible and expans-ible cage havingparts thereof engaging the sides of the rollers at points -within thecone surface passing through the axes ofthe lrollers for holding therollers againstV the inner surfaceofthe cup'hand for maintaining therollers in their positions relative'to each other, and the ridge of thec up operating to maintain the rollers and the cage within the cup. 4- yIn testimony whereof I have, hereunto signed my name vto thisspecification..
